Problem

The python client cannot communicate with the database after a clean install following the tutorial on osx.

Reproducing the error

from aquiladb import AquilaClient as acl                                                                                                                                   
                                                                                                                                                                           
# create DB instance

# convertDocument                                                                                                                                                          
sample = db.convertDocument([0.1,0.2,0.3,0.4], {"hello": "world"})                                                                                                         
                                                                                                                                                                           
# add document to AquilaDB                                                                                                                                                 
db.addDocuments([sample])

This leads to the following error message:

This is gRPC connection error. StatusCode.UNAVAILABLE does indicate that the AquilaDB python client can’t reach AquilaDB server (docker container). Can you make sure that the docker container is running? Also the port 50051 is accessible within your system?

Here’s how to deploy the docker image as a container: https://github.com/a-mma/AquilaDB/blob/develop/README.md#usage
